Well, there are several common themes. The idea of a shared past or a connection that goes beyond their current conflict is a popular one. This could be explored through flashbacks or revelations in the fanfiction. Another theme is the exploration of their individual growth. Link might grow in understanding of Ganondorf's motives, and Ganondorf might grow in his view of Link. And sometimes, there's a theme of an alternate reality where they are not enemies but allies or even friends, which can lead to very interesting storylines.
A possible theme could be the exploration of power and its corrupting influence. Ganondorf is often associated with a thirst for power, and Link has his own power in a different way. How they interact with power and how it affects their relationship could be an interesting theme. Additionally, a theme of prophecy or fate could be involved. If there are prophecies in the Zelda lore about their destinies, a fanfic could play around with how they respond to those prophecies, either by trying to fulfill them or defy them.
Finding 'Link x Ganondorf' mpreg fanfiction can be a bit of a challenge. Mpreg is a concept that not everyone is interested in, so the amount of such fanfiction might be limited. Additionally, it depends on how popular the 'Link x Ganondorf' pairing is within the fan community. Some fans might focus more on their adversarial relationship rather than a romantic or mpreg - related one. If you search on different fanfiction platforms, make sure to check the tags carefully to narrow down your search.
There might be. The world of fanfiction is vast and full of all kinds of creative and sometimes unusual concepts. However, it's not a very common or widely known trope in the general 'Link x Ganondorf' fanfic realm. Some fanfic communities might have such content, but it could also be considered a bit out - of - the - ordinary even within the fanfic world.
One common theme is the power struggle between them. Since Hichigo represents Ichigo's inner Hollow, there are often stories exploring how they battle for control within Ichigo. Another theme is the idea of self - discovery for Ichigo. Through his interactions with Hichigo, he can learn more about his own powers and identity.
One common theme is the eternal struggle between good and evil. Link represents good, and Ganondorf is the embodiment of evil, so their interactions often revolve around this fundamental conflict. Another theme is redemption. Some fanfictions explore the possibility of Ganondorf being redeemed or at least having a change of heart.
One common theme is the power dynamic between Link and Ganondorf. When Link gets hurt, it often shows how vulnerable he can be in the face of Ganondorf's power, which can create a lot of tension in the story.
I'm not very familiar with this specific type of fanfiction, but generally, themes could include the relationship between Ghirahim and Link evolving in a unique way due to the pregnancy. There might be themes of protection, as Link would be in a vulnerable state. Another could be the reaction of the characters in the Zelda universe to this unexpected situation.
One common theme could be the relationship dynamic between Link and Dark Link. Since it's an MPreg fic, there might be themes of unexpected parenthood and how they deal with it. Another theme could be the contrast between light and dark, as Link represents light and Dark Link represents dark, and how that plays out in the context of a pregnancy.
The theme of duality is quite common. They are two sides of the same coin in a way. Fanfics such as 'The Dual Nature' explore this concept. Batman's dark and brooding nature against Joker's maniacal and colorful chaos. Another theme is the mystery around Joker. Fanfics often try to dig deeper into his past and motives. 'Unraveling the Joker' is a fanfic that focuses on trying to understand what made Joker who he is, without any mpreg - related stuff. Also, the theme of hero - villain relationship is explored in a lot of fanfics, like 'The Hero and the Villain' which looks at how they are defined by their relationship to each other.
One common theme is the power dynamic. Since both Link and Ganondorf are powerful in different ways, a female Link changes the equation. For example, in some fics, her femininity is seen as a way to subvert Ganondorf's expectations of power.
